The underlaying question in this law is about estimating the monetary value of a piece of information and creating a market for selling information. As an example, here in Spain the master of Madrid Community's mayor has been deeply investigated, here that information has strong political implications, and produces monetary value for some political parties. A law can't be easily applied to Giants and ants, to huge actors and to individual bloggers, the model can't scale appropiately. So I would suggest just to impose a tax to huge actors and forget about creating a law that ranges from bloggers to google or twitter, those entities can't be measured with the same rule.

Googling about how to quantify in dollar the value of journalism, I found
